    • Facile: a System for Artificial Face Dataset Generation 

      Brambilla, Andrea; Colombo, Alessandro (The Eurographics Association, 2010)
      We present Facile, a system for the generation of artificial face datasets aimed to assist the training and evaluation phases of face related algorithms. Facile is able to generate, starting from a set of textured 3D faces ...
    • A Framework for Virtual Restoration of Ancient Documents by Combination of Multispectral and 3D Imaging 

      Bianco, Gianfranco; Bruno, Fabio; Tonazzini, A.; Salerno, E.; Savino, P.; Zitova, B.; Sroubek, F.; Console, E. (The Eurographics Association, 2010)
      Historical documents often undergo various changes over time, that alter their original state and reduce their legibility. Digital techniques are widely applied for document preservation, archiving, analysis and dissemination ...
    • Improving 2D-3D Registration by Mutual Information using Gradient Maps 

      Palma, Gianpaolo; Corsini, Massimiliano; Dellepiane, Matteo; Scopigno, Roberto (The Eurographics Association, 2010)
      In this paper we propose an extension for the algorithms of image-to-geometry registration by Mutual Information( MI) to improve the performance and the quality of the alignment. Proposed for the registration of multi modal ...
    • Manual Segmentation and Semantic-based Hierarchical Tagging of 3D models 

      Papaleo, Laura; Floriani, Leila De (The Eurographics Association, 2010)
      Today 3D objects have become widely available in different application domains, thus it is becoming fundamental to use, integrate and develop techniques for extracting and maintaining their implicit knowledge. These ...
    • Mixed Reality and Gesture Based Interaction for Medical Imaging Applications 

      Abate, Andrea F.; Nappi, Michele; Ricciardi, Stefano; Tortora, Genoveffa (The Eurographics Association, 2010)
      This paper presents a framework providing a collection of techniques to enhance reliability, accuracy and overall effectiveness of gesture-based interaction applied to the manipulation of virtual objects within a Mixed ...
    • Modeling Liquidus Hypersurfaces through Simplicial Complexes 

      Natali, Mattia; Attene, Marco; Ottonello, Giulio (The Eurographics Association, 2010)
      This paper describes an operational pipeline that exploits computational geometry to derive useful knowledge about the crystallization behaviour of materials composed of varying amounts of pure components. Starting from ...
    • Monitor-Based tracking system for Wide Augmented Reality Environments 

      Re, Guido Maria; Caruso, Giandomenico; Belluco, Paolo; Bordegoni, Monica (The Eurographics Association, 2010)
      In Augmented Reality (AR) applications, the technological solutions used for tracking objects in the real environment are generally related to the conditions of the environment and to the application purposes. The selection ...
    • Mutual Correspondences: An Hybrid Method for Image-to-geometry Registration 

      Sottile, Michele; Dellepiane, Matteo; Cignoni, Paolo; Scopigno, Roberto (The Eurographics Association, 2010)
      Image registration is an important task in several applications of Computer Graphics and Computer Vision. Among the large number of proposed approaches, currently there is no solution which is automatic and robust enough ...
    • Natural Interaction and Computer Graphics Applications 

      Iacolina, Samuel A.; Lai, Alessandro; Soro, Alessandro; Scateni, Riccardo (The Eurographics Association, 2010)
      Natural Interaction with computers has been a challenging topic of research since the very beginning of the digital era and refers to the possibility, on the user s part, of exploiting natural abilities to control the ...

    • Towards a Voting Scheme for Calculating Light Source Positions from a given Target Illumination 

      Zmugg, René; Havemann, Sven; Fellner, Dieter W. (The Eurographics Association, 2010)
      Lighting conditions can make the difference between success or failure of an architectural space. The vision of space-light co-design is that architects can control the impression of an illuminated space already at an early ...
    • Two Examples of GPGPU Acceleration of Memory-intensive Algorithms 

      Marras, Stefano; Mura, Claudio; Gobbetti, Enrico; Scateni, Riccardo; Scopigno, Roberto (The Eurographics Association, 2010)
      The advent of GPGPU technologies has allowed for sensible speed-ups in many high-dimension, memory-intensive computational problems. In this paper we demonstrate the e ectiveness of such techniques by describing two ...
